Figure 1From: Inhibitory effect of the combination therapy of simvastatin and pinocembrin on atherosclerosis in apoE-deficient miceIdentification of pinocembrin in propolis by MS analysis. A. Purify pinocembrin from the crude flavonoids of propolis. The retention time of the peak (the black arrow) was consistent with standard pinocembrin, and its purity reached 91.1% as determined by HPLC. B. The peak (the black arrow) on HPLC gave a major molecular ion [M + H]+ at m/z 256.394, which was consistent with standard pinocembrin.Back to article page
